How to use detectsurffeatures in Simulink

Hi guys!

I would like to use the Matlab Code from "Object detection in a cluttered scene using point feature matching" in Simulink. However I have a problem with the surf points object. Does anyone know how to use the "detectsurffeatures" function in simulink. You will find the error message and the code in the attachment.

According to my understanding, you are trying to implement the detectSURFFeatures function using a MATLAB Function block in Simulink. The function block takes an Input of the image to the detectSURFFeatures function and should output a SURFPoint object handle.

However, the MATLAB Function block in Simulink does not allow passing object instances through the Input/Output ports. You can refer the MATLAB documentation regarding the data types of function argument here.

For further information and understanding, you can refer to this previously answered MATLAB Question.
